I took a mechanical engineering class at GA Tech. The class was all about linkages. The professor was Harvey Lipkin. Rav Salanter's son, Yom Tov Lipman, also was into linkages. I thought that was such a great coincidence, I had to find out if they were related. Unfortunately, he was unable to find any connection, and it is unlikely that Yom Tov Lipman even had any children.Not sure what good a picture of my prof will help, but here it is anyway:http://www.me.gatech.edu/faculty/lipkin.shtml

I completely disagree; look again. The first two pictures look just like the man in the third picture aged a couple of decades. In addition, you can see that the man is blind in the left eye in both (which anon pointed out above).

I did, and still don't see the resemblance. The shape of the eyes in the first two, is different than in the third, and so is the nose. Also note the slightly curly hair in the third, versus the straight hair in the first two.Though aging a few decades changes the features a bit, the basic features stay the same. They don't become remarkably different.

Another important point. Rabbi Yitzchok Lipkin moved to Yerushalayim in his later years. There he (re?)married and bore a son R' Aryeh Leib, whose son was R' Chaim Yitzchok. The dress in the 2nd picture definitely doesn't fit the typical way of dressing in Yerushalayim in those days. Food for thought.

Hello all...I am the owner of the Branches of Mussar site. While it is nice to find such a man as Rav Salanter in your ancestry...I am more interested in MY ancestry than in being his descendant. The two pics of the older Yitzchok Lipkin are indeed of Yitzchok Lipkin...but, are they of a different Yitzchok Lipkin? I would be very interested in seeing the proofs you speak of about these being two different men.
